IMPROVEMENT IN GRATES FOR STOVES.

Specification forming part of Letters Patent No. 159,360, dated February2, 1875; application filed I December 16, 1873.

. declared to be a specification-of the same.

This invention is to allow for the removal of clinker and slate from afire without allowin g the fuel to fall down through the grate-bars. Theinvention is especially available upon cooking and other stoves, andranges, and in furnaces where the removal of clinker is of greatimportance as insuring a uniform and perfect combustion.

I make use of fixed bars of ordinary character, but about twice theordinary distance apart, and introduce intermediate bars made with hooksat the back ends, that hook over the rounded portion of the back bar,uniting the stationary bar. By this construction the grates can beseparated, and one grate can be lowered for removal of clinker, and theparts are made with facility, and do not require the hinge-pins at thejoints heretofore proposed for grates of this general character.

In the drawing, Figure 1 is an elevation of the grate of a stove orrange, with the secondary grate dropped down. Fig. 2 is a crosssectionof the same; the position of the secondary grate, when up in place,being indicated by dotted lines.

The grate-bars a a are permanent or fitted into place in any usualmanner. I have shown them connected with the front piece, b,

bars a a, and are removable. They are united by the front bar, d, andmade with hooks e at the other ends, passing above and hooking over thebar f, that connects the rear ends of the bars a. The bar at will, bypreference, be positioned so as to be in front of the plate b whenraised up, and hence out of the way in raking the fire. The hooked endse of the bars cc allow the grates to be easily separated or puttogether. The grates do not require hand labor in fitting them together,the parts being cast ready for use. In Fig. 1 the hook h is shown asadapted to catch below a lug, 1', upon the bar d, and in Fig. 2 aspring-latch, k, is shown that catches below the edge of the bar When inuse these bars support the fuel in the ordinary manner, and allow forthe tire being raked; but when there is any accumulation of clinker orslate the secondary bars are lowered and the pieces withdrawn, the bodyof the fuel, meanwhile, being supported by the stationary grate-bars aa, after which the movable bars are raised to place. The movable barsmay be the same width as the stationary bars, or they may be of greateror less width, so that the spaces between the respective bars, wheneither raised or lowered, will be adapted to the fuel made use of.

I claim The bar f, uniting the back ends of the gratebars a, and nearlyround, in combination with the intermediate bars 0, that are made withhooks e at their back ends, passing over the bars f, as and for thepurposes set forth.
